We Aussies are pretty proud of the various improvements we have over the UK and US systems. Our independent electoral commissions minimise gerrymandering. Our preferential voting system ensures more accurate representation. Mandatory voter turnout has a moderating influence on political campaigning and avoids voter disenfranchisement issues.
But you can't look at the last decade of federal politics in the country and say it has been much other than a joke. We've just per chance had Brexit and Trump happening lately which has made it seem less ridiculous in comparison.
Leadership issues aside, we need a federal anti-corruption body and a well-worded bill of rights. As it stands, the government has far more room to move than they should, and on many issues the opposition has been either useless or complicit.
